Implement Message Digest algorithm

SHA1 message digest for securing your string for storing into database.

Firstly create a method called sha1(String password). Here pass the password as a string as a parameter.

String sha1(String input) throws NoSuchAlgorithmException {

MessageDigest mDigest = MessageDigest.getInstance("SHA1");

byte[] result = mDigest.digest(input.getBytes());

StringBuffer sb = new StringBuffer();

for (int i = 0; i < result.length; i++) {

sb.append(Integer.toString((result[i] & 0xff) + 0x100, 16)

.substring(1));

}

return sb.toString();

}

Now just get the input from user and store it using this method into database

String shapassword = sha1(masterPassword.getText().toString().trim());
